title: Mitochondrial genome of the ringstraked guitarfish Rhinobatos hynnicephalus (Elasmobranchii: Rajiformes).
abstract: The complete mitochondrial genome of the ringstraked guitarfish Rhinobatos hynnicephalus is firstly presented in this study, which is also the first representative in the family Rhinobatidae. It is 16,776 bp in length and contains 37 genes and one control region as the typical gene arrangement and transcriptional direction in vertebrates. The overall base composition is 31.7% A, 26.8% C, 13.5% G and 28.1% T. The 22 tRNA genes ranged from 67 bp (tRNA-Ser2) to 75 bp (tRNA-Leu1). The origin of L-strand replication (OL) sequence was identified between tRNA-Asn and tRNA-Cys genes. The termination associated sequence (TAS) and the conserved sequence blocks (CSB 1--3) were recognized in the control region.
